The first step to this is to subtract 7 from both sides. The +7 and -7 cancel each other out leaving you with 3x=6 then divide by 3 on each side giving you x=2.
Answer: 2
4/2= 2
So your answer is 2
Answer:2+2x7
Step-by-step explanation:
We are asked in the problem to determine the inverse of the relation y = 3x + 12. first step is to express the equation in terms of y, that is y -12 = 3x, then exchange the places of x and y, that is x - 12 = 3y. This is the final answer
let x =the number
Step-by-step explanation:
81+x=3x-39
group like terms
81+39=3x-x
120=2x
120/2=2x/2
60=x
therefore x =60
